Abstract

An illuminated sign comprises a photoconductive plate and a series of light-emitting diodes of a type having a viewing angle of approximately 8° Being made from polycarbonate in a single piece, the photoconductive plate is inset from its back face, toward its front face but not through it, so as to define a series of indicia, each having a boundary. Each light-emitting diode is pressed into a recess opening at an outer periphery of the photo-conductive plate, between the front and back faces.
The recess orient the light-emitting diodes so that a part of the boundary of each of the indicia is disposed within the viewing angle of at least one of the light-emitting diodes and so that another part thereof is not disposed within the viewing angle of any of the light-emitting diodes. An opaque material covers the back face of the photoconductive plate, at least where the back face is visible through the front face thereof, except where the photoconductive plate is inset so as to define the indicia. A fluorescent material covers the indicia and is adapted to fluoresce at a color matching the color of light emitted by the light-emitting diodes when energized.
